I would like to know if epilepsy medications weaken skin tissue strength. Recently, I noticed that more bruising at times is occurring without even hurting myself and at times I noted dents from pressure points in some areas. After seeing my doctor regarding this, no clear cause was linked to an allergic reaction. However, I want to prevent injury due to skin damage. Currently, I am on Keppra, Dilantin, Aptiom and Clobazam. Dilantin is being phased out. What may be the medication-related cause of weaker skin tissue?
